This invention relates to automatic valves, and its general object is to provide a check valve that is positive in. operation under all conditions and positions thereof, in use, is

noiseless, will overcome all difliculties encountered with the fiat or disk valve now commonly employed, utilizes no springspr studs, is simple in construction, inexpenslve to manufacture and install, and is extremely eflicient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangsment of the several parts, to be hereina er fully described,

illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention indetail, reference will be had to the accompanying 2o drawings wherein like characters denote like or corresponding parts throughout the several' views, and in which:

Figure 1 is a view of my valve in elevation. 7

Figure 2 is a longitudinal sectional view taken therethrough.

Figure 3 is a transverse sectional view through the valve member.

Figure 4 is a view of the valve seat.

I Figure 5 is a similar view of the resilient element of the-valve.

Referring to the drawings in detail, the

- reference numeral 1 indicates the valve cas- 'dIlCfll in shape, with a reduced portion 2 at one end which is interiorly threadedwhile the outer side thereof is formed with flat faces to provide wrench engaging surfaces. The opposite end of the casing 1 is provided with exteriorly arranged screw threads for the urpose of accommodating the screw threads of a couplin 3 that is formed with'a flange at one en to hold a flan ed straining element 4 with respect to the ody as clearly shown in Figure 2.

The straining element is substantially conical in form and has a plurality of equidistantl spkaced slots 5 formed in the beveled -wa t ereof. The outer or small end of the straining element is closed.

ing which as shown is substantially cylin- The valve member per se includes what I term a seat 6 having a flange 7 formed with the lar e end thereof, and this flan e is disposed in contacting enga ement wit the flange of the straimng e ement whereb these parts are held in association throu l i the instrumentality of the coupling 3. T e valve which is formed from resilient material is likewise provided with a flange 8 arranged in engagement with the flange 7 of the seat 6 and between the exteriorly threaded end of the casing 1 and the flange 7 as shown. This arrangement secures and holds the valve which is indicated by the reference numeral 9 on its seat 6. The seat is of truncated conical formation, and has formed in its beveled wall, slots 10 that have walls inclined toward each other as best shown in Figure 2. The valve 9 as above set forth is ormed from resilient material such as rubber or the like, and where it is found necessary it may be reinforced with steel strips or other reinforcing means, but in the present instance is shown as havin a plurality of elongated ton es 11 forme with its outer surface, and t e valve is arranged with respect to its seat in a manner whereby these tongues are disposed in registration or ai ned with theslots 10, as best shown in 1 ure 3. The tongues have their ends bevele and the valve is of a size to snugly fit the seat 6, but due to the engagement of the exteriorly threaded end of the casing 1 with the flange 8 thereof the valve cannot become casually removed rom its seat. The small end of the seat is closed as shown.

From the above description and disclosure of the drawings, it will be obvious that when the valve is in use, the direction of flow of liquid will be throu h the slots 5 of the straining element 4, an the liquidwill force the valve 9 from its seat by passing through the slots 10 thereof, however the flow of liquid in a reverse direction will be prevented as the natural inherent resiliency of the valve will retain the latter on its seat, with the result the liquid can not seep be tween the valve and its seat.

It is thought from the foregoing description that the advant es and novel features of m invention will e readil apparent.

I desire it to be understoo that I ma?' make changes in the construction and in the combination and arrangfment of the several 7 parts, provided that suc changes fall within the scope of the appended claims.

What I claim is:

1. A valve comprising a casing, a truncated conical valve seat arranged in said casing and provided with slots in its tapered wall a truncated conical valve formed from resihent material and cover being aligned with said slots, and means for securing said valve and seat in said casing.

2. A valve of the character described comprising a casing having a reduced end interiorly threaded and formed with flat faces on its outer side to provide wrench engaging surfaces, the opposite end of said valve being exteriorly screw threaded, a flanged truncated conical shape valve seat arranged in said casing, a like shape valve formed from resilient material and fitting said seat,

a flange included in said valve and engaging the flange of the seat, a flanged valve straining element of truncated conical formation, and a coupling for securing the flanges of the straining element, the seat and valve together and the parts in cooperative relation, said valve seat being formed with slots, and the valve coveri said slots.
